Quick releasable vise



Sept. 23, 1969 R. A. MARSH QUICK RELEASABLE VISE Filed Aug 28, 1967 United States Patent 3,468,528 QUICK RELEASABLE VISE Ralph A. Marsh, Whiting, Iowa 51063 Filed Aug. 28, 1967, Ser. No. 663,647 Int. Cl. B25b 1/06, 1/16, 1/14 US. Cl. 269-223 7 Claims ABSTRACT OF THE DISCLOSURE Conventional vises require that the actuating handle be rotated each time it is desired to separate the jaw members so that the workpiece can be removed therefrom. The operation of the actuating handle requires considerable time and this is especially undesirable when workpieces of the same size are successively placed between the jaw members as in a production line environment.

Therefore, it is a principal object of this invention to provide a quick releasable vise.

A further object of this invention is to provide a quick releasable vise which permits the vise jaw members to be separated quickly without rotation of the actuating handle.

A further object of this invention is to provide a quick releasable vise having a quick release handle operatively pivotally connected to a threaded rod which extends through the jaw members, the quick release handle being movable from an unlocked position to a locked position.

A further object of this invention is to provide a quick releasable vise which is durable in use, refined in appearance and economical of manufacture.

These and other objects will be apparent to those skilled in the art.

This invention consists in the construction, arrangements, and combination of the various parts of the device,-

whereby the objects contemplated are attained as hereinafter more fully set forth, specifically pointed out in the claims, and illustrated in the accompanying drawings in which:

FIG. 1 is a perspective view of the vise mounted on a supporting surface such as a workbench or the like;

FIG. 2 is a side view of the device in a locked position, the broken lines indicating the relationship of the various components of the device when the quick release handle has been moved to its unlocked position;

FIG. 3 is a top view of the device in a locked position;

FIG. 4 is an enlarged sectional view as would be seen on line 44 of FIG. 3, the broken lines indicating the relationship of the components when the quick release handle has been moved to its unlocked position;

FIG. 5 is an enlarged sectional view as would be seen on line 5-5 of FIG. 3; and

FIG. 6 is an enlarged sectional view as would be seen on line 6--6 of FIG. 3.

The vise of this invention is generally designated by the reference numeral 10 while the numeral 11 generally designates a supporting means such as a workbench or the like to which the vise 10 may be detachably secured. The numeral 13 designates a jaw member having a workpiece engaging portion 15 secured to its upper end. A pair of bars 17 and 19 are secured to the lower end of jaw 3,468,528 Patented Sept. 23, 1969 member 13 at opposite sides thereof by welding or the like and extend substantially horizontally therefrom as best seen in the drawings. A jaw member 21 is pivotally connected to the other ends of bars 17 and 19 by a bolt means 23 extending therethrough and is provided with a workpiece engaging portion 25 secured to the upper end thereof. 7

A pair of spaced apart angles 27 and 29 are secured at their forward ends to jaw member 21 by welding or the like and extend horizontally therefrom. Angles 27 and 29 may be secured to the supporting means 11 by means of bolts 31 extending therethrough. Angle 27 is comprised of a horizontal base portion 33 and a vertical side portion 35 extending upwardly therefrom while angle 29 is comprised of a horizontal base portion 37 with a vertical side portion 39 extending upwardly therefrom.

The numeral 41 generally designates a quick release handle comprised of a pair of spaced apart arms 43 and 45 having a handle member 47 secured to and extending between the upper ends thereof. The lower end of arm 43 has a pin 49 secured thereto by welding or the like which rotatably extends through side portion 35 of angle-27. Pin 49 is not secured along the central axis of arm 43 but is slightly offset therefrom as best seen in FIG. 2. A pin 51 is secured to the lower end of arm 45' by welding or the like and rotatably extending through vertical side portion 39 of angle 29. As seen in FIG. 4, pin 51 is not secured to arm 45 at the longitudinal axis thereof but is positioned slightly thereabove as viewed in FIG. 4.

A threaded rod 53 extends through jaw members 13 and 21 and has a portion 55 rigidly secured to one end thereof by means of a threaded bolt 56 extending therethrough, the opposite ends of which extend therefrom. A handle 57 including arms 59 and 61 is secured to the bolt 56 by means of the opposite ends of bolt 56 extending through arms 59 and 61 and being maintained thereon by means of nuts 65 and 67. A knob 63 is secured to the other ends of arms 59 and 61 and the handle 57 may be rotated on the bolt 56 and with respect to rod 53 to cause the rotation thereof. A washer 69 is positioned between head portion 55 and the outer surface of jaw members 13.

Rod 53 rotatably extends through jaw member 13 and also rotatably extends through slot 71 in jaw member 21. As seen in FIG. 2, rod 53 is also permitted a small amount of vertical movement with respect to the jaw members 13 and 21. A nut assembly 73 is threadably mounted on rod 53 between angles 27 and 29 as seen in FIGS. 3 and 4. A pair of pins 75 and 77 are secured to and extend from opposite sides of nut assembly 73 and are pivotally secured to arms 43 and 45 at a point upwardly of the pins 49 and 51. As seen in FIG. 5, pins 75 and 77 are positioned at a point below the longitudinal axis of arms 43 and 45 while the pins 49 and 51 are positioned above the longitudinal axis of arms 43 and 45. A stop means 79 is secured to the rearward end of angle 29 to limit the downward movement of handle 41 as illustrated in FIG. 2.

In operation, the handle member 41 would normally be in a locked position as seen in FIG. 2. Handle 57 would be rotated to cause the jaw member 13 to be pivoted with respect to jaw member 21 to facilitate the insertion of a workpiece generally designated by the reference numeral 81 therebetween. When the workpiece 81 has been positioned between the workpiece engaging portions on the jaw members 13 and 21, the handle 57 would be rotated to cause jaw member 13 to be drawn toward jaw member 21. The rotation of handle 57 causes the rotation of rod 53 with respect to nut assembly 73 which thereby draws jaw member 13 towards jaw member 21. Nut assembly 73 is locked in the position seen in FIG. 4 inasmuch as the pins 75 and 77 are in a plane below that of pins 49 and 51 as illustrated in FIG. 5. Thus, the specific arrangement of the various pins creates a toggle effect which causes nut assembly 73 to be locked in its position until such time as handle member 41 is raised from its locked position illustrated by solid lines in FIG. 2 to the unlocked position illustrated by broken lines in FIG. 2.

When it is desired to quickly release the workpiece 81 from between the jaw members 13 and 21, it is simply necessary to raise handle 41 which causes the rod 53, nut

assembly 73 and the various pins to be pivoted to the position illustrated by broken lines in FIG. 4 thereby permitting the jaw member 13 to be moved away from jaw member 21. The workpiece 81 or a workpiece of similar size may then be reinserted between the jaw members 13 and 21 and handle 41 may then be pivoted to its locked position which will cause workpiece engaging portions 15 and 25 to securely hold the workpiece between the upper ends of the jaw members 13 and 21. It can be seen that the workpiece can be removed from or reinserted into the vise without the actuation of the handle 57. It is simply necessary to pivot handle 41 from its locked to unlocked position and vice versa.

Thus it can be seen that a quick releasable vise has been provided which permits a workpiece to be quickly removed from or inserted into the device without the time consuming task of rotating the actuating handle 57. Thus it can be seen that the device accomplishes at least all of its stated objectives.

Some changes may be made in the construction and arrangement of my quick releasable vise without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
